Chapter 7 Launch 7 Flight Maneuvers Flashcards
(36 cards)
Boxing the wake
- Let tow plane know
- Do it outside of traffic pattern at > 1000’ AGL
- Use rudders to hold corners - avoid slack
How do you position glider for unassisted launch?
Position down wing behind the upper wing (angled 20 degrees from centerline) so the tow will pull the glider into alignment and move the down wing first to give it lift.
What are the points on the runway?
Aim point is where you aim to touchdown with your glide path.
Initial Point is your actual touchdown point after you flair.
Adjust landing speed with ….?
Pitch (Trim)
Adjust landing spot with…?
Airbrakes / spoilers
What elevation does the roundout start?
5 - 10’
How do sideloads on main wheel occur?
Sideloads occur when the glider is not aligned with the direction it is traveling.
How is rollout direction controlled?
With the rudder. However once the tail wheel is on the ground the rudder has little effect.
Rollout requirements
Wings level
Direction control with rudder.
Back pressure on stick
Airbrakes deployed
Wheel brakes if necessary
Try to get off of runway.
What happens if the tail wheel is forced into the ground on landing?
Directional control with the rudder becomes less effective. Pitch forward to take load off of tail and allow rudder control
How are crosswind landings handled?
- Line up tracking with sideslip.
- Crab to stay lined with runway
- Straighten crab with runway just prior to touchdown.
Difference between side slip and forward slip?
Forward Slip = Roll and opposite rudder to maintain straight track.
Side Slip = Roll and slight opposite rudder to prevent rotating of heading
What does down wind landing do to landing speed?
Maintain normal IAS but ground speed will be faster.
How is rollout distance affected by downwind?
Distance increases as the square of the ground speed distance. Doubling groundspeed will increase landing distance by 4x.
What is the slope of a headwind vs downwind landing?
Headwind will be a steep slope. Approach leg should be shorter.
Tailwind will be a shallow approach. Approach leg should be longer.
How should airbrakes be applied at touchdown in a downwind landing?
Full airbrakes and aggressive wheel brakes
What steps should be done upon completion of landing?
- Move glider off of runway
- Put weight on wingtip or tie it down
- Close Canopy & cover
- Install control locks
- Cover pitot tubes
Hangar Storage requirements
- Chock wheels
- Weight on wing or wing dollies
What happens to roll at different bank angles?
Less than 20 degrees glider want to roll back to wings level.
20 - 45 degrees glider tends to stay there with stick neutral
> 45 degrees glider wants to continue rolling. Requires opposite stick
Diff in wind speed over each wing determines tendency
What should ALWAYS be done prior to turning
Clear the airspace
What causes adverse yaw?
Initial roll creates more lift and more induced drag on the upper wing. Drag pulls upper wing back.
A slip has too much ______ and not enough ——–?
Too much roll and not enough rudder. Yaw string goes to opposite side outside of turn.
A skid has too much ____ and not enough _____?
Too much rudder and not enough roll. Yaw string goes in direction inside of turn.
When rolling into a turn, the glider has a tendency to pitch ____?
Down
